MICHAELBROWN, OF GATESVILLE, TEXAS PRESS.

SPECIFICATION forming part 0f Letters Patent N0. 753,539, dated March 1, 1904.

Application filed July 10, 1903. Serial No. 165,021. (No model.) Y

To a/ZZ whom it may concern:

Be it known that I, MICHAEL BROWN, a citizen of the United States, residing at Gatesville, in the county of Coryell and State of Texas, have invented certain new-and useful Improvements in Presses, of which the followy 'ing is a specication.

This invention has relation to means for compressing hay, clover, fodder, grass, and like edible fibrous material into bales for convenience of handling, storage, and transportation.

The pressis of the double-acting type, comprising two baling-chambers, a plunger working in each balingchamber, and actuating means for alternately advancing and withdrawing the plungers.

The present invention deals more particularly withthe actuatingmeans, the same consisting of rebounding plungers, a rack-bar attached to the rod of each plunger, and a toothed sector arranged for alternate coperation with the rack-bars for forcing them into the baling-chambers.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is tobe had to the following description and drawings hereto attached.v

While the essential-and characteristic features of the invention are susceptible of modiication, still thepreferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a press embodying the invention. i Fig. 2 is a top plan view, the sweep and the cross-bar of the frame supporting the upper end of the sector-shaft being omitted. Fig. 3 is a view similar to Fig. 2, showing the parts differently arranged.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The press comprises two baling-chambers 1 and 1, diametrically arranged upon opposite sides of a medial longitudinal line. These baling-chambers may be of any desired formation and are provided'near their inner ends l with feed-openings 2 2, preferably formed in the top side. Plungers 3 38L are arranged to operate in the respective baling-chambers, and their stems or rods 4 4 are provided with cog-teeth 5 5SL for coperation with the complemental teeth of the sector 6, secured to the lower end of the vertical shaft 7. The plungers 3 3a' are held in a given position by springs 8 8, which serve to return the plungers to an initial position when released from the advancing or compressing force. Transverse strips 9 9 are notched to receive the rods 4 4, so as to direct them in their movements.

These strips 9 9"L also act as stops to limit the movement of the plungers on the return stroke. Guide-pulleys 10 10a and 11 11' are disposed upon opposite sides of the respective plunger-rods 4 4L to give proper direction thereto and insure intermeshing of the teeth 5 5sb with the teeth of the sector 6. The baling-chambers may be secured to any suitable support, as the bed-piece 12, which consists of a platform or frame of any formation. The vertical shaft 7 is journaled at its lower end in the bed-piece 12 and near its upper end' in the cross-piece 13 of a frame comprising said cross-piece and uprights 14.

The sector 6 is secured to the shaft 7 in any manner so as to turnl therewith, and a sweep 15 is secured to the upper end of the shaft 7, so as to cause rotation thereof when applying turning force to the sweep.

In order to reduce the length of the press for convenience of storage and transportation, it is proposed to construct the bed piece or frame 12 of sections, which may be hinged or detachably connected in any manner. When the component parts are properly assembled,

the plungers 3 3ab occupy a position at the inner ends of the respective baling-chambers, so as not to obstruct the feed-openings through which the baling-chambers are charged with the material to be formed into bales. Upon imparting rotary movement to the sweep 15 the plungers are alternately advanced by engagement of the teeth of the sector 6 with the cog-teeth 5 5a. Normally the cog-teeth 5 5 occupy a diagonal arrangement. Hence one plunger only can be advanced at a time, thereby affording opportunity for lcharging the hailing-chamber whose plunger is at rest. When the advancing plunger reaches the limit of its forward movement and the teeth of the sector clear the cog-teeth of the plunger-rod, the latter is quickly returned to a normal position by the resetting or rebounding spring. Just before disengagement of the last tooth of the sector from the cog-teeth of the advancing plunger the tooth at the opposite end of the sector makes engagement with the cog-teeth of the other plunger-rod. Hence the sector is at all times in engagement with the teeth of one plunger-rod or the other, and there is no time in its rotation when it is wholly disengaged from both plunger-rods. The-baling operation is-continuous, since during the compressing of the charge in one baling-chamber the other baling-chamber is receiving a charge, and vice versa.

Having thus described the invention, what is claimed as new is- 1. In a press, the combination of baling-v chambers, plungers operating therein, rods connected with the plungers and provided with cog-teeth, means for returning the plungers and rods to a normal position, and a toothed sector arranged between the plunger-rods in the'plane thereof and having its toothed portion of such circumferential length as to engage witlr the cog-teeth of one plunger-rod prior to disengagement from the cog-teeth of the other plunger-rod, substantially as set alternate actuation of the plungers, substantially as specified. r

In testimony whereof I aiX my signature in presence of two witnesses.
